The SB Series Insert Bearings (Wide Inner Ring Set Screw Locking Spherical Ball Bearings) are dedicated insert bearing units for mounted bearing applications. Featuring a wide inner ring and a spherical outer surface, these bearings can be used with various cast iron housings (such as UCP, UCF, UCFL, UCT, etc.) to achieve self-aligning functionality. The bearing uses set screws to fasten the inner ring onto the shaft.
